Bridge in Ocrkavlje is a continuation of research and analytical work and process on documenting bridge structures at the Imperial road in Bosnia or džada, transversal already in ancient time, established on the territory of the present-day Bosnia and Herzegovina. Among the sixteen processed, there are three bridge structures that are first time treated in this way in term of protection, and whose documentation did not existed. Researching of the last one of the three bridges, the one in Ocrkavlje, confirmed the hypothesis about the belonging of these structures to the “architecture of purposes", as a version of vernacular architecture, the spontaneous dealing with problems at the level of experiential and intuitive, as in a basic postulate of builders or dunđerski work.
